' To all whom it may concern:

Be it known that I, GUs'rAv DI'ECKMANN,

a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented-new and useful Improvements in Foldable Drying Cabinets, of which the following is a specification.

This invention relates to a foldable drying cabinet.

lit is one of the objects of the present invention to provide a simple, substantial, cheaply manufactured, foldable drying cabinet which is particularly adapted for use in kitchens and small laundries where space must necessarily be considered.

Another object of the invention is to prodischarged therefrom.- Further objects will hereinafter appear.

Theinvention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figurel' is a central vertical's'ection, in side elevation, of the cabinet, showing it'in the extended position. Fig. 2 is a plan section on the line'm-m, Fig. 1. Fig. 3 is a sectionsimilarl to Fig. 1, showing the cabinet in the folded position. Fig. 4 is a plan viewof the cabinet, showing it in the folded position. Fig. 5 is a detail of the top supporting latch. Fig. 6 is a detail vertical section of on of the hollow pivot members.

Referring to the drawings, A 'indicates the folding cabinet in general and B a wall or support to which the cabinet is suitably secured. The cabinet in general consists of a" stationary rear section 2, to, which side ex.-

tensions/3 and 4: and a top section. 5 are rigidly secured. The side extensions 3 and 4, together with the top section 5, form a pocicet which is adapted to receive the heater and other parts of the cabinet when this is collapsedor folded, as hereinafter described. The side panels of the cabinet are in this instance h ngedly supported, as at 3 andd il on the stationary slde extensioIlS 3 an Each side panel is, however,

centrally divided, as at 6, and the two sec- Speciflcation of Letaflatent. Application filed J une 2, 1914i. serial No. 8423M.

- tions thus formed are connected together I gin es 7, This-permits the side panels to e and 7' to assume the position. indicated in Figs. 3 and 4-. The front panel of the cabinet, indicated at 8, is supported by the. side panels through means of hinges 9, so that it will move in and out as the panels are folded orextended. The front panel is otherwise provided with a pair of doors 9 and 10 mounted uponhinges 11, through which admission may be gamed to the cabinet. The top of the cabinet is supported and secured quite similar tothe side panels;

- that is, the top is centrally divided, as at 12,

and the sections thus formed are connected together by hinges 13'. The inner edge of the top is supported by hinges 14 to the top section 5, and the outer section of the topis adapted to be carried by latches 15 mounted on the inner sides of the side panels. The other section of the top is also supported by latches, as indicated at 16. Each section of the top is thus independently supported with relation to the side panels.

When closing or folding the cabinet, it is accomplished by opening the front doors!) andlO. The latches 15 are then depressed and the front pivoted section of the top will then be permitted to drop down in ,the direction of arrow a. It is then swung inwardly into the dotted line position indicated at 17 for the purpose of automaticallv releasing the latches 16. The inward movement of the front section of the top to thedotted line position indicated at 17 causes the outer" edges of same to engage with inclined faces Med inwardly about the hinges 3 P position indicated in Fig, 3.. The bottom of the cabinet is in the instance shown as consisting of a metal pan 19, which is pivotally mounted, as at 20 and 20, in the lower ends of the stationary side sections 3 and 4. Su'itably secured at about the center of said pan is a suitable form of burner 21, and entirely I inclosin same is a'hood- 22 which is connected t' rough a flattened flue 23 with a chamber. 24, Connecting said chamber 24 with the pivot oints 20 and 20., which are hollow, are disc arge flues 25 and 25. The

burner, indicated at 21, is preferably supplied by gas through a flexible-hose conlowered into the position indicated in Fig. 1.

Running parallel with the sides of the pan, and projecting a suitable distance a above the bottom of same, is a pair of battleplates 28 and 29, one being mounted on each side, and connecting .the outer ends of the channelsthus formed with the hood 22 is a pair of inlet fiues 30 and 31. ,The pivotpoints 20 and 20 are hollow and will thus form communication with outside flues C and the channels form (1 between the battle lates 28 and 29 and he sides of the pan. he air for drying fpurposes is admitted through a series 0 Y perforations 32 formed in the bottom of the pan directly under, the flue 23. The baflie plates also prevent the direct escape of the fresh air admitted through the perforations 32 bcfore it has become heated and performed its required function.

The operation will be as 'follows: If the cabinet is standing in the folded position shown in Figs. 3 and 4 and it is desired to extend it into operating position, it is accomplished by first releasing a pair of side hooks 33, then pulling the front panel 8 1n an outward direction which'is limited when the side panels assume the straight position. T he bottom or pan 19 .is then lowered down and the inner section of the top panel is raised until it is engaged by the latches 16.

The outer se tion is next raised until it iscngaged an supported bythe latches 15. A wire section or false bottom 3%, hingedly secured to the rear section -2 of the, cabinet, isthen dropped down and is supported by legs 35. The flexible gas hose connection 26 is then connected and-the burner started. Secured to the front and side panels at their upper and lower ends are angle-iron strips 40; the lower strips formin a support for the pan, while the upper strips form a stop or butt which, not only limits theupward movement of the cover sections but also aids .to form a tight joint between the cover and Y the front and side panels, which prevents leakage or escape of heat at theupper end of the cabinet. The lower supporting strips also have the same function, that as, they prevent the admission of cold air around the edges of the pan The latches 15 and ed in tapered blocks 15 and. 16*. These are provided both as guides to bri'ng'the cover sections into engagement with-their respective supporting latches and"v as-spacers or liners which hold the ccver sections in j'uxta position between the side panels.

Air to supply the burner is'gadmitted through thcinlet flue's {30 and 3 1 from the 16 are shownas mountside channels formed between the sides of the pan and thebaffie plates 28 and 29. The

products of combustion from the burner will then flow out through the fiue 23, chamber 24 and discharge flues 25 and 25" and will finally escape through the hollow pivot connection 20' and 20, which are connected with the outside flues C and chimney, or the like, not here shown, or may escape directly into the room.

The hood 22, together with the dues 23 and 25 and the hood covering chamber 24, will thus become thoroughly heated and fresh air from the outside will be admitted through the perforations 32 formed in the bottom of the pan. This air passing around the flue 23 and hoods 22 and 24 will become thoroughly heated and will consequently rise up through the center of the cabinet to finally become deflected by the top. The air graduall cooling by coming .in contact with moist clothing or similar articles suspended by rods indicated at 36, will thus gradually cool and will settle down along the interior surface of the side panels and will finally enter the side channels formed between the battle plates 28 and 29 and the sides of the ,pan. The'air thus partly cooled and moistened by contact with the clothing is partly consumed "by entering through the inlet flues 30 and through the hollow pivot connections 20 and 20" fresh dry air is in the meantime continuously entering through the perforations 32. A continuous supply of fresh, dry,heated air is thus supplied while the cooler and moistened air is partly consumed by the burner or permitted to escape through the connections 20 and 20. The clothing or other articles suspended within the cabinetor supported upon the screen 34; lStllllS quickly and thoroughly dried.

Referring to Fig. 6, it will be seen that the ends of the fiues 25 and 25 are preferably extended into the. mainoutlet fiues C and turned up as indicated at 41. This construction greatly increases the suction through the hollow pivot connections, as the products ofcombustion are directed right up into the main outlet flues. A more or less forced draft and siphon action are thus produced with consequent draft increase through the hollow pivot connections where most of the moist cooled air escapes.

The cabinet, when not in use, may be quickly folded by first opening the front doors 9 and 10 and releasing the outer sectionof the top by depressing the latches 15. Thejinne'r section of the top is then released .by-. swingingfthe outer section toward the dotted line position indicated at 17, which automaticallydepresses the latches 16to release the inner section of the top. The pan is next raised into the position indicated in Fig. v The released top sections arethen folded in toward their-ear section of the eabithis position by the hooks 33or other means.

The cabinet consumes very little speed-when folded, and may be folded or extended with very little effort, and is of such simple construction that it may be handled and su'ccessfu-lly operated by any one.
